RADIATOR GAP.

Application filed April 26, 1922.

T all whom it may concern.

Be it known that I, ELASHA D. CULLIsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented a new and useful Radiator Cap, of which the following is a specification.

This invention relates to a cap for radiators, one of the objects of the invention being to provide a cap which will be held yieldingly on its seat so as to completely close the filling opening, the pressure of the cap upon the seat being adjustable readily.

A further object is to provide a radiator cap which can be quickly shifted away from its seat so as to give convenient access to the opening. I

Another object is to provide a structure of this character the springs of which are housed and thus protected.

It is a well known fact that the ordinary screw cap used on automobile radiators is not satisfactory because the threads become mutilated, considerable time is required to screw or unscrew the cap, the cap is usually so hot that it cannot be comfortably handled, and it is easy to lose the cap.

The present invention is designed to overcome all of the foregoing disadvantages and provides a very simple and inexpensive but efficient structure which can be applied readily.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with n the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure l is a side elevation of the cap in position on the filling neck or collar of a radiator, the position of the cap when open being indicated by dotted lines.

Figure 2 is a section on line 2-2, Figure 1.

Referring to the figures by characters of reference 1 designates the usual filling neck or collar of a radiator, the same being pro vided, in the present instance, with a V- shaped bearing edge 2 forming a seat for Serial No. 556,777.

the cap constituting the present invention. It is to be understood, however, that this hearing edge can be of any other desired shape.

Secured in the neck or collar 1 at-diametrically opposed points are anchoring screws or studs 3' each of which is engaged by an eye 4 formed at one end of a rod 5. Each rod is slidably mounted within a sleeve 6 closed at its lower end, as shown at 7 while the upper portion thereof is exteriorly screw threaded as indicated at 8. The two sleeves 6 extend through and are adjustably mounted within ears 9 extending in opposite directions from a cap 10. A. groove 11 is formed in the bottom face of the cap and adapted to receive the edge 2 of the neck or collar 1.

Seated within each of the sleeves 6 is a coiled spring 12 extending around the rod 5 therein. One end of the spring bears against the closed end of the sleeve while the other end is restrained by a nut 13 threaded on the rod 5. Thus by adjusting the nut the compression of the spring can be varied and the cap caused to bear on the edge 2 with any desired pressure. The sleeves 6 are threaded into and extend downwardly from the end portions of a tubular handle 1 open at its ends and bearing at its center on the cap 10.

The springs 12 are normally under coin pression and, consequently, hold the cap to its seat. When it is desired to shift the cap so as to give access to the neck or collar 1 the handle 1% is pulled upwardly to raise the cap and cause the sleeves 6 to slide on the rods 5. Thus the springs 12 will be placed under further compression but sufficient clearance will be provided to enable the cap to be swung laterally and downwardly relative to the neck or collar and to a position such as indicated, for example, by dotted lines in Figure 1. The tubular handle 1 1 is kept cool because air is free to circulate therethrough and, therefore, the cap can be handled without causing dis-, comfort. hen it is desired to replace the cap on its seat it is merely necessary to reverse the foregoing operation.

While the device has been described as particularly useful in connection with radiators, it is to be understood that it can be employed wherever it is desired to use a sealing cap capable of being quickly placed in or removed from position.

What is claimed is 1. The combination with a neck providing a seat, of a cap, sleeves adjnstably mounted in the cap, yieldingly restrained elements slideble in the sleeves and piv0telly anchored to the neck, and a handle en-- gagged and held by the sleeves.

2. The combination with a neck providing a seat, of a cap normally bearing on the seat, sleeves edjustably mounted in opposed portions of the cap, members slida-ble Within the sleeves and pivotally anchored to the neck, springs within the sleeves, means EIClJUStilbl) engaging said members for regulating the compression of the springs, and 1;)
